TPMS Acting Up

Alright so I bought my 07 Sierra a few months back and didn't have any problems out of it for awhile. Then I started to get a "check right rear tire pressure" message every time I start the truck along with the TPMS light illuminated. All tires are fine however. Took it to a tire shop here and he tested all my sensors and said they're all fine. Told me to leave battery unhooked for awhile and try to reset the system that way. Didn't work for me. Occasionally I'll start the truck and the light and message won't come up initially, but with a little driving, sure enough it pops up again. Doesn't hurt the driving of the truck or anything, it's just more annoying than anything at this point. Anyone have this problem/know any solutions to it? Thanks

if those are the original batteries in the TPMS sensors in the rims then they are for sure going bad after 8-9 years. I always thought that the batteries were replaced when they did the TMPS rebuild thingie at the tire store but they are not. It's not part of the process.

Yep - was just going to say the same thing as Colossus.

 

I didn't think the batteries were replaceable - figured they made them as throwaway units, like so many parts are today.

 

My new scan tool (Autel Maxisys MS906TS) shows battery life in each sensor when it's scanned. It also shows temperature, which surprised me. If those sensors are temperature-capable, then why didn't GM put that parameter in the DIC? Would've been a great feature to have, especially when towing something heavy.

It was my understanding that they were made as throw away units as well and the batteries aren't replaceable. Maybe my tire shop guy was just wrong in telling me all the sensors were fine but he ran a scan tool over all of them and said they were okay. Just getting annoying and want to get it figured out lol

      OCI, not when but why?

      By Atlas · Posted

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.

      I apologize, I missed this post, at risk of going off CURRENT TOPIC.   I'm not saying it is BS, I'm questioning how much information is being held back. GM is NOT going to spell out exactly every parameter in the algorithm. Liability, intellectual property, etc.    I'm not naive enough to believe that it is as simple as revolutions, coolant temperature, miles, time; are you?    I don't do irrational either, and boiling the OLM down to four simple values that I could code in an afternoon (I'm not a coder) is irrational - unless it suits your agenda to ignore it.

      Chris 21 I appreciate your constructive response. !!  😉😉😉   The 6.6 is gas.  Correct me if I’m wrong but by recalibrating the speedo you’re correcting the shift points of the transmission on these trucks.?.

      That is a huge misconception.     Bigger does not always equal safer.  Modifying does not make it safer either, with exceptions.   Think of this.  Your truck in stock form is capable of emergency maneuvers, proper stopping distances, its handling is designed around the factory wheel/tire packages, etc.   37s and a lift?  Now you've affected your braking distances, handling and ride control.  You've raised your center of gravity higher.  Your front visibility is now obstructed more than stock, same for your rear.  Does it look cooler?  Yes.  Does it now work as good as it did from factory on road?  NO.       As for my mention of exceptions?  Say you had a sedan or crossover.  They typically come with all season tires.  If you swap out for a performance all season or a summer tire, you improve your car by lowering its stopping distance (better braking because of traction) and improve the handling (regular and emergency) of the vehicle.  That is an actually improving modification.  My old 2019 LD 1500, I ran UHP all season tires on 20in wheels in a factory offered size.  It improved all aspects of how it drove over the Duratracs it came with from the factory in the stock 18" tire.
